At the same time on-line updates work well.
Do you mean in the
same system, the normal updates are working and the full VPS won't? Or, do you mean that normal updates are working as a general statement?
If the normal updates are working in the same computer, then maybe the problem was when downloading the full VPS, or some other "glitch" while performing the specific update. I would suggest cleaning the web browser's cache and downloading the VPS again, then reboot before applying the full VPS update (at least for this time, so to test it).
If we are talking about a different system, then running anew the setup.exe of avast (no need to uninstall, just run it over) and
then reboot should repair the full updates, but it may be necessary to update the definitions again after the setup.exe (again, with the respective reboot in between).
As I understand there were some issues with off-line update files. Are they resolved?
The problem (a couple of weeks ago) was already resolved and the full VPS update was re-posted. If it has a problem again, that's another story. I have not tested it myself since its last reposition on the website (
http://www.avast.com/download-update, but the real size is about 41+ MB).
